Which pair is best for producing maximum-saturation green?

Correct answer: Green-biased yellow and green-biased blue

Green is produced by mixing yellow and blue pigments. To obtain maximum saturation, both pigments should lean toward green, because this minimises unwanted red or orange influences that would neutralise the mixture. Option A is therefore correct. Option B contains opposing biases, while red and blue do not provide the clean yellow-blue combination required for vivid green; red and yellow produce orange instead.
